Drinking Water Treatment with UF Membranes: Meeting WHO and EPA Standards

Ultrafiltration has revolutionized drinking water treatment by providing an absolute physical barrier against particles, bacteria, protozoa, and most viruses. UF-based drinking water systems consistently produce water meeting WHO guidelines and US EPA standards, making them ideal for surface water treatment, groundwater under direct influence of surface water, and distribution system protection.

Pathogen Removal Performance

UF membranes achieve outstanding pathogen removal: greater than 6 log (99.9999%) removal of bacteria like E. coli and Cryptosporidium, greater than 4 log removal of Giardia cysts, and 2-4 log removal of viruses depending on membrane pore size. TheWay's 0.03 micron PVDF membranes provide reliable multi-barrier protection that meets or exceeds regulatory requirements for pathogen removal credits.

System Design for Drinking Water

Drinking water UF systems incorporate coagulation pretreatment for enhanced NOM removal, automated backwash and CEB for fouling control, continuous integrity monitoring for regulatory compliance, and post-treatment disinfection (UV or chlorination) for distribution system residual. TheWay pressurized UF modules (TW-UF-4040 and 8040 series) are ideal for drinking water treatment from 10 to 10,000 m3/day capacity. Contact info@thewaymembranes.com for design support.
